Sun Patent Trust v. Roku, Inc.

UPC_CFI_59/2025

In this UPC decision, Sun Patent Trust sought an Anti-Anti-Suit Injunction (AASI) against Roku, Inc., aiming to prevent Roku from pursuing related anti-suit or anti-enforcement injunctions in US courts. The court ultimately denied the request for provisional measures. The ruling emphasized that while a prior warning is not strictly necessary, the claimant must demonstrate a genuine risk of irreparable harm; here, the court found that the requested AASI was likely futile and risked prejudicing the claimant's rights without proper preliminary steps.

What the Court Held — Ratio Decidendi

The court ruled that a prior warning (Abmahnung) is not a prerequisite for an injunction request, but its absence can lead to the applicant bearing costs if the defendant immediately provides a non-infringement declaration. Crucially, the court found that because the claimant's requested Anti-Anti-Suit/Anti-Anti-Enforcement Injunction was likely futile and risked undermining the claimant's rights without prior warning, the request for provisional measures must be dismissed.
